1.1 Name plate, CE and body markings

The stainless steel name plate is undetachably riveted to

the body.

If the operator attaches his identification, it must be

ensured that the valve matches the application in

question.

Example of name plate with CE marking:

No CE marking is permissible for the sizes 15, 20 and 25;

the name plate therefore has no CE marking.

Example: Name plate for control data

If heavy-duty bellows are installed, another name plate

indicates this:

HD - BVA = Heavy-duty bellows with support rings of

stainless steel

HD - BKo = Heavy-duty bellows with support rings of

PTFE/carbon

Body identification:

The following are visible on the body according to DIN EN

19 and AD 2000 A4:

 Nominal size

 Rated pressure

 Body material

 Manufacturer's identification

 Melt number/Foundry identification

 Cast date

 Arrow for direction of flow

According to AD 2000

According to ASME B 16.42

When used in the area of application of ASME or

ANSI/ISA, the low temperature of ASTM A395 is limited to

-20°F (-29°C).

When used in the minus temperature range, the

regulations applicable in the country in question

must be observed.

Notes:

The next lower kv100/Cv value can also be achieved with special plugs without changing the seat .

This is important if the kv100/Cv value is subsequently changed as only the plug then has to be replaced.

Conversion into Cv (US gpm) = kv100 x 1,165.

1.8 Opening and closing forces required

The values specified in the tables apply to a seat/plug

material of modified PTFE.

With other materials, e.g. PTFE/carbon, higher closing

forces are required. Please inquire at manufacturer's.

If the maximum p is < p2, p2 is used in the tables.

observe the application limits acc. to the pressure-

temperature diagram in Section 1.4.

 A mechanical travel stop is required in the area

marked.

It is provided when

p > 10bar/145 psi to Seat-Ø 15-50 mm

p >6 bar/87 psi to Seat-Ø 65 mm

2 Notes on safety

This operating manual contains fundamental information

which is to be observed during installation, operation and

maintenance.

It must be read before installation and

commissioning!

For valves which are used in potentially explosive areas,

see Section 3.

Installation and operation are to be performed by

qualified staff.

The area of responsibility, authority and supervision of the

General hazard symbol!

People may be put at risk.

Safety symbol! The ball valve and its function

may be put at risk if this safety symbol is not

observed.

It is imperative to observe warnings and signs attached

directly to the ball valve and they are to be kept fully

legible.

Non-observance of the notes on safety may result in the

loss of any and all claims for damages.

For example, non-observance may involve the following

hazards as:

 Failure of important functions of the valve/plant.

 Risk to people from electric, mechanical and chemical

effects.

 Risk to the environment through leaks of hazardous

substances.

2.1 Intended use

Richter bellows-sealed globe control valves of the series

RSS/F are pressure containing components in accordance

with the Pressure Equipment Directive (PED) for the

passage and shut-off of fluids. The valves are suitable for

vapours, gases and non-boiling liquids of group 1

according to the PED and have a corrosion-resistant

plastic lining.

Sie werden zur Regelung von korrosiven, reinen und

hochreinen Flüssigkeiten, Gasen und Dämpfen in Chemie-,

Pharma-, Lebensmittel- und industriellen Prozessen

eingesetzt.

Solids can lead to increased wear, damage to sealing

surfaces or to a reduction in the service life of the valve.

The operator must carefully examine in the event of

operating data other than those provided whether the

designs of the valve, accessories and materials are

suitable for the new application (consult the

manufacturer).

2.2 For the customer / operator

When using the valve, it must be ensured that

 actuators which are retrofitted are adapted and

designed to suit the valve

 hot or cold valve parts are protected by the customer

against being touched

 the valve has been properly installed in the pipe

system

 the usual flow rates are not exceeded in continuous

operation.

This is not the manufacturer's responsibility.

Loads caused by earthquakes were not allowed for in the

design.

Fire protection to DIN EN ISO 10497 is not possible (plastic

lining and plastic components).

2.3 Improper operation

The operational reliability of the valve supplied is only

guaranteed if it is used properly in accordance with

Section 2.1 of this operating manual.

The operation limits specified on the identifica-

tion plate and in the pressure-temperature

diagram must under no circumstances be

exceeded.
